White noise outshines silence by providing a stable acoustic environment. Silence magnifies events like door slams and external sounds, such as traffic. A constant sound offers good cover for these sorts of events; therefore, during sleep, the experience is longer and deeper, and its duration, concentration-wise, is greater in comparison.

Understand the science of masking. Silence causes gaps in acoustic signals. These gaps unpredictably amplify sudden sounds. White noise fills the complete spectrum of frequencies. The brain does not scan for gaps. This contributes to a decrease in stress response. The body produces less cortisol. This frees energy in the body for healing.
